Police have issued a warning after people selling items on Facebook were targeted with fake money.
Officers from Staffordshire Police said there had been multiple reports since Christmas of counterfeit notes circulating in the county.
The force said a woman selling on Facebook marketplace was duped on 28 December after a buyer handed over £1,000 in counterfeit notes in exchange for a mobile phone.
On Monday, a seller in Tamworth reported he sold a guitar on the same platform and accepted £300 in notes, which were also fake.
